Stu Posted May 4, 2008 Share Posted May 4, 2008 No, you can't clean them. Soot on them is normal. Link to comment Share on other sites More sharing options...
scortmad Posted May 4, 2008 Share Posted May 4, 2008 sorry stu but i must disagree in 13 years of repairing cars that fail mot's because of a faulty lambda sensor 50% of the time cleaning it with a wire wheel will correct a incorrect signal from a lambda sensor Link to comment Share on other sites More sharing options...
Danzetec Posted May 5, 2008 Share Posted May 5, 2008 The lambda sensor is a consumable item that lasts for something like 60-70k miles iirc. Cleaning it as scortmad suggests MAY prolong its life a little but your soon be replacing it anyway Link to comment Share on other sites More sharing options...

speedy Posted May 5, 2008 Share Posted May 5, 2008 just getting the car hot and up to temperature with a good thrashing down the road will burn of any soot around the sensor and pass an emission test providing its not a rancid air filter etc causing the problem Link to comment Share on other sites More sharing options...
